Testimonials

What Our Clients Say?

  • 72 M +
  • 2,300 +
  • "Finally found a shop that handles Al7075-T6 properly. The complex manifolds had zero burrs in the deep cavities. Shipping to Stuttgart took 1 day longer than I liked, but the ±0.005mm tolerances were spot on. Proper 5-axis work here."

    Hans Weber

    - Senior Design Engineer

  • "Crazy fast turnaround on our suspension uprights. Honestly, I was worried about the thin-wall sections vibrating during milling, but they came out super stiff. A bit pricey for shipping, but for this kind of rapid prototyping quality? Totally worth it."

    Justin Miller

    - R&D Project Manager

  • "Quality of the milled impellers is very high. Surface finish is clean, no tool marks. We had a small issue with the report format at first, but you fixed it fast. Good for low-volume auto parts. Will reorder soon."
